ABC is a right-angled triangle.
AC= 16cm
Angle c= 90• (degrees)
Size of angle b: size of angle A = 3:2
Work out the length of AB
Give your answer to 3 significant figures.

your answer is b.

x = 33.9

y = 65.6

step-by-step explanation:

place r′ so that qr′ is parallel to the tangent.

now we get that ∠r′py=∠pr′q, where y is on the tangent, on the opposite side of p from x.

also, because of the symmetry, ∠r′py=∠qpx.

finally, note that no matter where we place r, as long as it's on the correct arc, we have ∠prq=∠pr′q.

stringing all these equalities together, we end up with ∠prq=∠qpx.

this picture will show how its going to look like.
